See the backside of Olivia Munn’s Psylocke costume for X-MEN: APOCALYPSE.

As “pick up” filming for X-MEN: APOCALYPSE continues in frigid Montreal with director Bryan Singer, actress Olivia Munn instagrammed a new behind the scenes photo showing the backside design of her Psylocke costume.

As one of Apocalypse’s villainous horsemen, Psylocke uses her enhanced abilities to battle any opponent that gets in her way. Munn recently told Entertainment Tonight that it was very “important” for her to do her own stunts.

“That was me from the beginning to the end,” she said about the scene of her character slicing through a flying car. “That was a really cool thing to feel like when I showed up on set I was like, “Oh wait, I can do this! Throw me onto a wire, give me a sword – I’m good!’

“Psylocke is such a powerful, lethal character. It was important to me that I was able to do all of the stunts because the more believable it is, the better it is for the audience — and the only way to make it believable is for me to actually do it.”

‘X-Men: Apocalypse’ comes to theaters on May 27th!
